Stacey, I forgot to mention that I already disabled system restore early on in the process, and will leave it off until I am sure that this is resolved.
Our home LAN is behind a hardware firewall so I don't know that I need another.
From what I understand, this is just a little java script that is hiding somewhere and opens IE windows (popups) to particular web sites when there is an internet connection.
The only info I can find is to turn off system restore, dump all the above mentioned files/caches and reboot. It should be gone, but it's not
